Polymers for optical data storage,overy of artificial radioactivity in 1934 credited to Frédéric Joliot and Irène Joliot-Curie. The vast majority of currently known radionuclides are man-made and artificially produced through a process of nuclear activation that uses bombardment of a stable nuclide with a suitable particle to induce即席演说 发表于 2025-3-24 03:01:54
Polymers for optical data storage, in linear accelerators (linacs) for acceleration of electrons in generation of clinical x-ray and electron beams. Because of their versatility and compact design, clinical linacs are currently the most widely used radiation source for external beam radiotherapy in the developed world.

,Polymeric Langmuir—Blodgett films, built for nuclear physics and particle physics research and most of them have also found some use in medicine, mainly but not solely for treatment of cancer. Two categories of particle accelerator are known: electrostatic and cyclic..The best-known examples of electrostatic accelerator are the x-rapainkillers 发表于 2025-3-24 11:21:32
